This condensate is collected in a separator where the oil and water naturally separate due to their immiscibility. Rigorous quality control is then essential.
Ensuring Quality: The Essential Oil Testing Process
Primary Extraction Methods The most common and historically significant method for extracting essential oils is steam distillation. For many essential oils, a period of aging in inert containers like steel or glass is beneficial.
Gas chromatography and mass spectrometry are sophisticated analytical tools used to verify the oil's chemical constituents, ensuring its purity and identifying any potential adulterants. This creates a waxy mass known as a concrete.

The steam vaporizes the volatile aromatic compounds, and the resulting vapor mixture is then condensed back into a liquid. The plant material is washed in a solvent, typically hexane, which dissolves the essential oils and other aromatic compounds.
